New Species of Snapper Discovered in Brazil

15.03.2007
Popular Game Fish Previously Was Mistaken For Common Species

A popular game fish mistaken by scientists for a dog snapper is actually a new species discovered among the reefs of the Abrolhos region of the South Atlantic Ocean.

The international science journal Zootaxa recently published the discovery of Lutjanus alexandrei, a new snapper species that belongs to the Lutjanidae family, by researchers Rodrigo Moura of Conservation International (CI) and Kenyon Lindeman of Environmental Defense. The study published in Zootaxa provides a revised key for identifying all Lutjanus species in the western Atlantic, along with evidence that the new species completes its life cycle in different but interdependent marine habitats, such as coral reefs and mangroves.

“This discovery that a large, popular fish is a species new to science shows how little we know about the oceans that surround us,” Moura said. “It looks like other snapper species found in the Caribbean and eastern United States, as well as the dog snapper caught by fishermen here in Brazil, but it is a distinct species with different markings and color.”

Twelve species of the family Lutjanidae, including the new discovery, are now identified in the western Atlantic Ocean. They include Lutjanus griseus and Lutjanus apodus, two species restricted to the Caribbean and eastern coast of the United States but previously believed to occur in Brazilian waters until the discovery of Lutjanus alexandrei.

The new species also has been mistaken for Lutjanus jocu, known as the dog snapper, a popular commercial fish in Brazil. According to Moura and Lindeman, the discovery shows the need for more comprehensive studies of Brazil’s reef fish populations, particularly in the northeastern region that includes the Abrolhos area, which contains the nation’s largest concentration of coral reefs.

The new species is named for 18th-century naturalist Alexandre Rodrigues Ferreira, whose extensive work in the Brazilian interior remains largely unknown. Moura and Lindeman spent five years observing Lutjanus alexandrei to analyze its characteristics and determine the distinct features.

It occurs from the state of Maranhão to the southern coast of the state of Bahia, and its habitats include coral reefs, rocky shores, coastal lagoons with brackish water, mangroves, and other shallow habitats. Juveniles requiring more food and protection live in mangroves, then migrate to reef habitat and deeper areas as adults.

“Several species spend some of their lives in these different yet connected habitats,” Lindeman said. “That’s why it’s so important to develop integrated conservation strategies that include mangroves, deep reefs, and other interdependent ecosystems.”

Some of the research was conducted under the Marine Management Areas Science program, a CI initiative intended to improve marine biodiversity conservation and the welfare of local communities. In Brazil, the MMAS program was established in the Abrolhos region in October 2005.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
